Codename One Allows Developers to Create Apps Across a Spectrum of Devices

Your mission, should you choose to accept it: Design an app and port it for use across an ocean of devices.

Seems easy, right? Ask any developer, and dollars to donuts, they will laugh and explain why it is not that easy. First, there are myriad programs associated with multiple mobile device operating systems -- Adobe AIR, Aqua, Convertigo, GeneXus, and so forth. Even though those development programs can be used for a host of devices, they do not let developers create one app that can be ported magically to every device.

Codename One lets users develop apps that are easy to port to any platform.What's the excuse to avoid developing now?(Source: Codename One)

There are several ways of getting around this problem, but they are neither simple nor absolute. The first method is to create a driver for each platform (Android, iOS, etc.) that provides access to the devices internals (GPS, accelerometer, and other sensors) using Python, Java, or other scripting languages. Another method is to create a tool (program) that can translate the original app to work on different platforms. This method is similar to what Codename One has managed to accomplish with its latest platform release.

Instead of using HTML5 or other languages, the platform is based on Java and features a GUI interface for developing user applications. Developers can create native applications for a wide variety of mobile platforms, including smartphones, tablets, and netbooks/Chromebooks. (The original intent of Java was to create a virtual machine that would run on any platform.)

Codename One recently left the beta stage, where approximately 100,000 users created an astounding 1,000 apps for the mobile market. The company recently released version 1.1 and offers a robust client library for app development, a designer tool (complete with a Java5-based GUI interface, theme designer, editor, etc.), a simulation environment (extremely handy for testing apps in development), and cloud-based services to help get users' apps to the masses.

Another handy feature makes use of standard IDE tools for debugging applications, which allows developers to weed out problems while in the build stage.

Chen Fishbein and Shai Almog, who created the Lightweight User Interface Toolkit at Sun Microsystems, started Codename One, which is actually a sort of extension of the Widget toolkit. The company says that, since the release of its latest version of Codename One back in March 2013, the SDK has been downloaded more than 200,000 times to rave reviews.

Codename One also recently released the Maker mobile app, which allows those with no developer skills to build their own applications using only their mobile devices. The app is generated in Codename One's cloud-based build servers. The software can almost guarantee that the mobile device market will be flooded with apps for just about everything you can imagine, even if you're not a developer.

This is great, Cabe. There is tons of value in making things easier for design engineers. This is a nice new trend. Control engineers are experiencing the same thing. More capability, less original programming.

Rob, You are 200 percent correct. The trend I've been observing is programming tools are easy to use with emphasis in developing the product not in software development. Crowd funding sources such as Kickstarter are allowing entrepreneurs the opportunity to build great products. Programming tools like Codename One allow these entrepreneurs to rapidly build prototypes as well as production units with ease. All product feature/functions can easily be developed without the burden of becoming a hardcore programming. I'll definitely be checking out this tool for my own mobile/smartphone applications. Great article Cabe!

It is quite strange that, such an exceptional app is not approved by Apple, as professional developers working at iphone app developers newyork I have found code name an exceptional tool for development.

Yes Codename tools most popular among the developers. I am working as a developer in California IT company and love to use this tool.Because this tool helpus to reduce time and pain during development.My friends those are working as website development dubai in Dubai, also using codename tool.

Really helpful tool, I like its interface its quite user friendly, I am utlizing in my SmartIO Content Transfer App Project, I am using it quite smothly no big bug fixes required which reduces lot of time.

Cabe, Very informative. Interesting that Java is competing with the HTML5 apps that have been making so much noise in mobile. Would be interesting to know if debugging "translated" code becomes a problem in development.

Cabe, If you go to the free Udemy training session for Codename One, the founder of the mobil app development software states the software usage on Apple devices is still under negotiations. I assume Apple wants sometype of royalties based on developers creating apps using Codename One software. Hopefully, this isn't the case. Great article and resource!!

Cabe, I checked out the Udemy Training videos for Maker Codename One and its quite an impressive mobile app development software package. I really found the Form Builder feature of the tool to be exceptionally powerful because of the customization capabilities you can make to your app. Last, the Preview feature allows you to test the app right on your mobile device prior to the final build which is good for debug/modifications. Its a really cool app! Thanks for bringing this resource to the Design News community Cabe!

Virtual Reality (VR) headsets are getting ready to explode onto the market and it appears all the heavy tech companies are trying to out-develop one another with better features than their competition. Fledgling start-up Vrvana has joined the fray.

A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.

While every company might have their own solution for PLM, Aras Innovator 10 intends to make PLM easier for all company sizes through its customization. The program is also not resource intensive, which allows it to be appropriated for any use. Some have even linked it to the Raspberry Pi.

solidThinking updated its Inspire program with a multitude of features to expedite the conception and prototype process. The latest version lets users blend design with engineering and manufacturing constraints to produce the cheapest, most efficient design before production.
